Chromosomes in a bacterial cell can be $1-3$ in number and:
  1. are always circular
  2. are always linear
  3. can be either circular or linear, but never both within the same cell
  4. can be circular as well as linear within the same cell

Solution

Prokaryotic cells contain their chromosome as circular entity. Usually, the entire genome is a single molecule of circular DNA but often the number may vary up to three. Related Theory Bacterial chromosomes and plasmids are double-stranded circular DNA molecules and are often referred to as covalently closed circular DNA, or cccDNA.
